working with CAD data coordinate systems

I've read through all of the Help Docs about CAD data, and especially with respect to working with the coordinate system.

It's a bit complicated; "if this, then do that", or you could "do this or do that" depending on certain scenarios.

...So, is there a documented Workflow or some Diagram for this?
Seems to me this would be a lot easier to understand if there were..

More specific questions are:

The Help Docs keep referring to creating a necessary PRJ file. I know what this is because of my experiences with Shapefiles, but I do not see that file anywhere even when the coordinate system is defined (assigned).
...With that, is this true even when the CAD data is exported to a Geodatabase ...that seems weird.
If the CAD data units are in inches or millimeters, should I still define the (PRJ) coordinate system in units of feet or meters, respectively?
Why is the name of the tool 'Change Coordinate System' to create the PRJ file when it opens the 'Define Projection' tool? ...I'm just curious so I can follow the logic.
What's the difference between using the 'Transform to Suggested Location' and 'Move to Display' options?
What's the difference between using the 'Transform Edit' tool and the 'Georeferencing Control Points' tool?
And, what does having a World file eliminate the need for?

Thanks, CCE
